The substrate setup is shown below. the GND is on the bottom layer.
I would like to add a small plane on the "Cond" layer which is connected to the "bottom" layer by vias,
which means the small plane is also part of the GND layer.
What I tried is to draw a circle on the "cond_cond2" layer. but I'm not sure if the way I did is correct, and how to prove if
small plane on "Cond" layer is connected to "bottom" layer through the drawing circle on " Cond_Cond2 " layer.
